2. 1. Tools for Autonomous Process Control

   Author : Anders Wallén; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sequential control; software architectures; fast set point response; spectral estimation; frequency domain identification; relay feedback; non-linear system identification; Autonomous Control; Process Control; Grafcet; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : There is an ongoing trend towards higher automation level in process control systems. The purpose of a plant is to manufacture some product at a high production rate with a consistent quality, while minimizing the use of resources in terms of energy consumption, raw material and labor.

4. 2. Towards Improved Control of TMP Refining Processes

   Author : Karin Eriksson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; dynamic modeling; process limitations; simplified decoupling; Refiner; refining zone temperature; internal interconnections;

   Abstract : The need for improved energy usage has become a key issue in all industrial sectors. In the energy demanding production of mechanical pulps many efforts havefocused on design development, but regarding control of refiners, there is still a potential for improvements. READ MORE

5. 3. Design and Implementation of Object-Oriented Model Libraries using Modelica

   Author : Hubertus Tummescheit; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modeling languages; thermo-fluid systems; process modeling; process control; control systems; thermo-hydraulic systems; non-linear models; model library design; object-oriented; modeling; simulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

   Abstract : This thesis describes basic models for thermo-fluid systems and the implementation of the models using a flexible object-oriented structure in the ThermoFluid library. Model libraries provide an excellent way to package engineering knowledge of systems to be reused by non-experts. READ MORE

6. 4. Probing Control of Glucose Feeding in Escherichia coli Cultivations

   Author : Mats Åkesson; Institutionen för reglerteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; control engineering; robotics; Automation; dissolved oxygen; acetate; glucose feeding; robotteknik; Escherichia coli; Process control; fed-batch cultivation; reglerteknik; Biotechnology; Bioteknik;

   Abstract : Production of many proteins can today be made using genetically modified organisms. One of the most frequently used host organisms is the bacterium Escherichia coli. A difficulty encountered in cultivations of E. coli is the accumulation of the metabolic by-product acetate which inhibits cell growth and production of a desired protein. READ MORE

7. 5. Machining Monitoring and Control : Based on Parametric Modelling

   Author : Mats Bejhem; KTH; []
   Keywords : Machining Control; tool condition monitoring; in-process dynamic stability monitoring and control; optimisation of cutting conditions; MC; DSP; TCM; NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : The objective of this work was the development of aMachining Control prototype system for turning, whichintegrates three fundamental aspects of Machining Controltechnology: Monitoring, Control and Optimisation. MachiningControl refers to the detection and automatic handling ofdisturbances in machining processes. READ MORE
